PRINTING-GAGE.

Specification of Letters Patent.

Application filed. October 10, 1907, Serial No. 396,799. Renewed June 19, 1908. Serial No. 439,455.

T all whom it "may concern:

Be it known that we, WILLIAM DUKE, Sr.,

I and WILLIAM DUKE, Jr., citizens of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Printing-Gage, of which the following is a specification.

Our invention consists of a gage for setting sheets to be printed true and uniform on the platen of a ress, the construction of the same being ereinafter described and the novel features pointed out in the claims.

Figure 1 represents a perspective view of a printing gage embodying our invention. Figs. 2 and 3 represent top or plan views thereof, certain parts being in different positions in the two figures. Fig. 4 represents a vertical section on. line a;-a;, Fig. 2. Figs. 5 and 6 represent perspective of a detached part respectively in reversed positions. Fig. 7 represents a perspective view of a portion of the device. Fig. 8 represents a section on line y-y, Fig. 3. Fig. 9 represents a section on line zz, Fig. 3. Fig. 10 represents a section on line a a, Fig. 2.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings z-A designates a base plate, and B designates an elbow lever, which is pivotally mounted thereon, it being noticed that the lower limb B of said lever has on its pivotal end the head C, which rises angular from said end and being adapted to enter the opening D in said plate, and engage with the cross-bar or flange E on said plate at the rear of said opening, said head 0 thus being adapted to turn on said bar as a fulcrum. Connected with the plate A and bearing against the limb B is the spring F, whose tendency is to elevate said lever to its normal position, and hold it engaged with said bar E.

G designates a slide, which is adapted to freely overhang the limb B and to pass over the same in its advance motion, see Fig. 3, it being connected with the parallel followers H, which are fitted in the guides J, which are located on the upper face of the plate A and firmly secured thereto. The ends of the fol lowers H opposite to the slide G, have con nected with them the gage plates K, which when advanced are adapted to contact with the edge of the paper, and the latter is placed true on the tympan sheet similar to that shown in the Letters Patent of the United States No. 841,948, granted to us on the 22d day of January, 1907.

Pivotally connected with one of the followers H is the toggle lever L, which is also pivotally connected with a follower M, the latter being fitted in the guide N, which extends parallel with the guides J and is connected with the base plate A. A spring P is located within the follower M, which is hollow or tubular, and is adapted to bear against the same and a fixed member. A spring Q is lo cated within each follower II, which is hollow or tubular, and is adapted to bear against the same and a fixed member, said springs serving to restore the followers, and consequently the gage plates K, to their normal positions.

Connected with the joint of the limbs of the lever B, is the spring S, whereby the upper limb of said lever may be held in elevated position, as most plainly shown in Fig. 4.

The inner sides of the guides J are partly cut away to allow the ends of the slide G to travel therethrough, and partly occupied by the shoulders T, which are struck up from the adjacent sides of the said guides and'so located as to cause said slide to abut thereagainst when the latter has completed its throw or advance motions, for a purpose in be hereinafter described.

It will be seen that when a rcglet or other proper part of a press is lowered, it bears against the lever B, and gradually lowers the same to contact with the paper. As said reglet or part continues its descent, it bears against the toggle lever L, thus lowering and straightening the same and thereby advancing the connected follower H and the gageplato K. As said follower is connected with the opposite follower, the other gage plate K is simultaneously advanced, and thus both plates contact with the edge of the paper, the latter then being placed true on the tympan sheet.

It will be noticed that the advance motion of the slide G is limited by coming in contact with the shoulders T, so that the plates K come to a dead stop against the paper before printing, but to prevent strain on the parts, the follower M under the pressure of the spring P remains comparatively at rest until the follower H has advanced to full extent, but when the advance motion of the plates K cease, the toggle lever L continues to descend, which it does to full extent. Then meansfor: guiding: said; carriers, a device the follower M receives motion in they opposite direction to.the follower H, as indicated by the arrow, Fig. 3, thus relieving said lever L and connected members of the device. of. strain, and preventing breaking or fracture of. thesame..- As: the springs 13,. Q are compressed by the motion of the respective follower, asso'on as the reglet rises, the levers B, L are released, whereby they return to their'nonmal!positionsandEwitli:them the connected followers and gageplates-..

Attentionds directedtostlre fact that a singlea toggle lever: is. sufficient. to advance the plurality of. gagesplates; and; that only one of! the followers H requires a spring to return the gage plates to their normal positions, whi'l'ethe spring; which bears on; t'herfollower Mi isisuffinienttouc'anse the quick: elevation of the togglelever and its'restbrationto normal position; Theplate A.h&S prongson fingers U projecting fbrwardly therefrom, the same being adapte'd to pierce and. enter'the tymp'an sheet, as ourpatent. hereinbefore referreditm I/Vliile'ewe have specified certain means for carrying out our improvements, we do not wisliz to. h'e liinited exactly to' the same, but desire. to. make such. changes as may come within the scope-of: the novelty involved.

Having thuszdescrihed our invention,.what we claim as new and desire to secure by Letters Patent, is:;

1.. Ina gage of the-character stated, a pluralit'yi'oii gageplates, carriers therefor, a-common connecti'onfor said carriers, means for guiding'saidicarriers, a single 1 device adapted to: be operated by a: member of: a. press for advancing. said. plurality of carriers and plates, and. resilient. means for. returning the same.

2;. In aagage of the character stated-,.a.plu-

reality of gageplate's, carriers therefor, amovable connection common to said. carriers, means for guiding said carriers, a device adapted to? be operate'd by a member of a press, a. singleileven having. alimb pivotally connected. with one of' said carriers, and a supplemental follower with which. the other limb .ofsaidleven is pivotally connected.

In aigage' of the character'stated, a pluralityoffgage'plates,carrierstherefor, a movable connection. common. to said: carriers,

adapted to be operated by a member of a press, a: single lever having; a limb pivotally connected with one of said carriers, a supple mental follower with which the other imb of said lever is pivotally connected, and means on one of the first named carriers with rier, a shoulder on said guide, and meansfor advancing said carrier, said. piece being adapted to abut: against saidshoulder'for-ming a dead stop for said gage plate in operatlve position.

6. Ina gage of the character stated; a gage plate, a carrier therefor, aguide'for said: carrier, a sliding piece connected: with said5carrier, ashoulder'on said. guide, meansfor advancing said carrier, said piece being adapted: toabut against said shoulder, forming a deadstopfor said gageplate in operative po sition, and a resilient member connected with said advancing means havingamotion in reverse direction to said carrier when said dead'stopis occasioned.

74 In a gage of the character stated, a. gage plate, means for advancing andv returning the same, a base on which: said: means are mounted, and a: lever adapted to primarily hold the paper'to be gagechsaid lever having a limbadaptedto befreely connected with a portion of said base and turn thereon as a fulcrum: and means bearing against the under side of saidlever near its fulcrum...

S. In a gage of the character stated, a base, a lever adaptedto primarily hold: the pap-erto be gaged, said base having acrossbar, and'said. lever having'a head adapt'ed to be fulcrumed on'the under side of'said crossbar and means bearing upward'onthe under side of said. lever to keep it engaged withs-aid bar.
